UNITED STATES PATENT OFFICE.

WALTON STANLEY TOPE, OF LONDON, OHIO.

HOTBED-SASH PROP.

Specification of Letters Patent.

Patented Nov. 30, 1920.

To all whom it may concern:

Be it known that I, VALTON S. Torn, a citizen of the United States, residin at London, in the county of Madison and State of Ohio, have invented new and useful Improvements in Hotbed-Sash Props, of which the following is a specification.

The object of my present invention is the Uprovision of a simple, easily positioned and safe prop through the medium of which a sash of a hot-bed may be supported and held open to a greater or less extent as conditions require.

To the attainment of the foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof: ,7

Figure 1 is a view on a small scale illustrative of the application of my novel hotbed sash prop.

Fig. 2 is a side elevation of the prop per 86 on an enlarged scale.

Fig. 3 is a longitudinal vertical section through the upright of the prop, and showing the arrangement of the sash-supporting platform relatively to the upright.

Fig. 4 is a horizontal section taken in the plane indicated by the line 4+4: of Fig. 2, looking downwardly.

Fig. 5 is a detail elevation illustrative of the inner side of the upright of the prop.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Among other elements my novel prop comprises a base 1, designed to be superimposed on the frame of a hot-bed. The said base 1 is preferably 4' inches in length, l; of an inch thick, and 2 inches wide, and is provided, at its upper side with a longitudinal central rib 2 that is 9; of an inch high at the upright 3 and is gradually tapered in height and thickness to the outer end of the base 1 where it is merged into the upper side of the base as shown.

7 The upright 3 is fixed with respectto and rises at right angles from one end of the base 1. The said upright 3 is preferably 12%} inches in height, 2 inch wide at its inner side and {50f an inch in thickness, and in its inner side and longitudinal center it is-provided with ten (more or less) notches 4; the lowest notch being g of an inch deep and the notches being gradually increased in depth as they approach the upper end of the said ippright, the upper notch being of an inch ceep.

The prop also comprises an adjustable platform 5. The said platform 5 is preferably T1; of an inch thick, 1!; inches wide from its forward end to an intermediate point 6 in its length, and is tapered from the said intermediate point 6 to its rear end where it is preferably of an inch wide. On its forward end portion the platform 5 is provided with a cross-strip 7, designed to preclude a sash slipping off the platform. In the platform 5 is an oblong aperture 8 that is preferably of an inch wide and of an inch long, and is disposed in the center of the platform. At its under side the platform 5 is provided with a clutch 9 that is preferably of an inch in length and of an inch in thickness and is inclined as shown.

As will be understood by comparison of Figs. 2 and 4;, the platform 5 is arranged on and supported by the upright 3, and when the hot-bed sash is laid on the platform, the clutch 9 enters one of the notches 4 in the upright 3 and thereby firmly holds the platform 5 and the sash thereon against down ward movement. In this connection it will be observed that when the platform 5 is clutched to the upright 3, the platform will have the natural slope of the sash.

Having described my invention, what I claim and desire to secure by LettersPatent, is:

A prop for hot-bed sash, comprising a base and an upright fixed to and rising at right angles from one end of the base, the base having at its upper side a longitudinal central rib that extends from the inner side of the lower portion of the upright, and" the upright having in its inner side a vertical central series of notches gradually increased in depth as they approach the upper end of the upright, and a platform with rear and forward arms, having an oblong aperture loosely receiving the upright, and an inclined clutch at its under side to seat in the notches of the upright and also having on the upper side of its forward arm at the end thereof a cross-strip.

In testimony whereofI afiix my signature.

WALTON STANLEY TOPE.
